Fastpass cookie problem

We had (successfully) tested the URL method for using Fastpass by creating a link.

I am now trying to implement the cookie method, but not having any luck.

I am currently creating a cookie for the domain '.nursetesting.com', path '/', expiring tomorrow named 'fastpass' with the contents retrieved by the URL method you provide.

We've created a CNAMEfor getsatisfaction at 'faq.nursetesting.com', and when I display the cookie information for faq.nursetesting.com (eg, while I'm using the getsatisfaction site via the CNAME), the fastpass cookie shows up.

I'm also loading the widget from faq.nursetesting.com.

Regardless, whether I use the widget or the site directly, I am asked to log in.

Any ideas what I'm doing wrong?
